I know that it is used Alan but I don't understand how it works as both products are basically stable and inert
However I would propose the following chemical raction chain (just my assumption, no guarantee whatsoever): the salt (NaCl) may slightly react with the metal and produce ferric or ferrous chloride (Fe Cl3 or FeCl2, highly reactive and slightly acidic) and the sulphur may react with it and produce black iron sulphide (FeS) giving the "warangan" effect on the blade.
